Works flawlessly

Never have had a problem with this app (2FAS Auth). So nice not to be bombarded with useless ads and information within the app. Never had a problem with getting codes or using them. My phone disappeared for several hours earlier this year when my husband was in the hospital. So thankful I had this app and use it for really important information. For whatever reason, someone “found” my phone & turned it in to Security. If you want extra security on your devices, this app is a great solution!

Great little app

This is the best authenticator app I've used and it doesn’t look like it steals my data to boot. Eager for that cross sync functionality they keep teasing so I can add all my logins say on my iPhone and they’ll show up on my iPad too. More importantly though I would love if this had a watch app. It’s such a short simple interaction I’m sure it would be a great fit for a watchOS app. Keep up the good work.

Clean and Smooth Authenticator

I love the simple design and functionality of this app compared to others. My only concern is what happens if the app is accidentally deleted or my phone is stolen. I think you should be able to set up an account with a login just in case a scenario like that happens so I wouldn’t be locked out of all my accounts that require a 2FA.
